Preparing for a flood event

Flood mapping and information is used to help inform emergency preparedness planning. The mapping helps our community Get Ready. 

As storm season approaches, it’s a good time to go online and check your property using our emergency preparedness mapping.

Residents are encouraged to look at the locations where they live, work, or where friends and family members may go to school. Look at how flooding affects the routes often travelled. It’s important to have a backup plan or know the alternative routes you can take.

Think about how your property might be affected by different flood events. Consider any changes you might need to make to prepare for flooding now or in the future and increase your own resilience.

Community awareness and education

Flood mapping helps the community to understand how flooding and overland flow may affect aspects of your everyday life, at home, at work, at school or on the road. Understanding and acting on this information helps build a strong and resilient community.

Historically, most Queensland towns and communities were established on or near a floodplain. As a result flooding is likely. With this in mind, understanding flood risks to your property and your local area, helps build community resilience to possible flood events.

Disaster Hub

Council's Disaster Hub services the community during disaster events and help build our community's emergency preparedness for events like flooding, all year round.

Emergency preparedness flood mapping products

Riverine flood maps (minor, moderate, major and extreme flood events)

Riverine flood maps show the effect of widespread and prolonged rainfall over a large catchment area. Riverine flood events may cause elevated water levels in our rivers and creeks for several days. Flash flooding can also occur following intense localised rainfall and with little warning.

These maps provide an estimate of how and where water will rise during a flood event. This information is important for emergency preparedness as it assists with disaster management and planning, for both council and our community.

The mapping is divided into four categories to represent likelihood and flood risk.

Flood Likelihood	Minor	Moderate	Major	Extreme
Annually	40%	10%	1%	0.05%
Over 70 years	100%	99.9%	50%	3%

Storm tide maps (storm surge maps)

This mapping presents surge heights above the highest astronomical tide. It shows the effects of additional surges from the ocean during meteorological (storm) conditions.

This information is important for emergency preparedness. It assists with disaster management and planning, for both council and the community.

Responding to the Queensland Floods Commission of Inquiry (the Inquiry) recommendations

The updated flood mapping and information responds to the Inquiry's recommendation that local governments provide risk-based mapping so residents, professionals and local government can more clearly know, prepare for and manage flood risk.
